Product Description
Kepco KLP-75-33-1200 Programmable DC Power Supply – 1200 Watt Laboratory Grade
This used Kepco KLP-75-33-1200 is a high-performance programmable DC power supply featuring Kepco’s proprietary Hyperbolic Power technology. This 1200-watt laboratory-grade supply delivers exceptional flexibility by providing full rated power over an expanded operating range, not just at a single point .
The KLP series replaces the need for multiple power supplies by automatically recalculating voltage and current limits along a constant-power hyperbolic curve. This means the single KLP-75-33 operates as a 0-75V/16A supply OR a 0-36V/33.3A supply—and every 1200W volt-ampere combination in between .

Hyperbolic Power Technology – The Key Advantage
Conventional power supplies have a single maximum power operating point. The KLP’s breakthrough constant-power hyperbolic limit provides a greatly expanded choice of maximum power volt-ampere combinations :
-
Point A: 75V @ 16A (full voltage, reduced current)
-
Point B: 36V @ 33.3A (full current, reduced voltage)
-
Point C: Any 1200W combination between A and B along the hyperbolic curve
This autoranging or extended range capability means one KLP can replace multiple conventional supplies, saving both money and rack space .
